70% yenzvimbo yepasi rose igungwa. Kubva pachiteshi chegungwa kusvika kumabhiriji akanaka emahombekombe uye kurima kwemvura yemugungwa kwemazuva ano, vanhu vakagadzira pfuma isingaverengeki vachishandisa gungwa guru iri. Zvisinei, zvishandiso zvakanaka zvakakosha kuti vabudirire. Zvinhu zvakajairwa zvakaita sehuni, simbi, nekongiri zvinowanzova nemari yakawanda yekugadzirisa uye hupenyu hushoma. Kuwana zvinhu zvitsva zvinogona kutsungirira ngura yemvura yegungwa, kusvibiswa neUV, kukurwa kwemafungu, uye biofouling kwenguva yakareba kwakakosha. High-density polyethylene (HDPE), ipurasitiki yeinjiniya, yakabuda nekushanda kwayo kwakakwana, ichiva chinhu chakanakira kuvaka zvivakwa zvemugungwa.
Sei HDPE yava chinhu chakakodzera?
1. Kuramba Kuora: HDPE inodzivirira maasidhi, maalkali, uye munyu, inodzivirira ngura yemvura yegungwa, uye haiparadzi ngura sesimbi yakajairika kana kuora sehuni.
2. Inogara kwenguva refu uye Inodzivirira kukuvadzwa: Kunyangwe pa -40 degrees Celsius,Mapepa eHDPEdzinochengetedza kusimba kwadzo, dzichidzivirira zvinobudirira kukanganiswa nengarava uye dzinotsungirira kukurwa kwenguva refu kubva mujecha.
3. Kukwanisa Kusanamatira: Nzvimbo yakapfava zvikuru yemapepa eHDPE inoita kuti zviomere zvipenyu zvakawanda zvemumvura kunamira zvakasimba.
4. Mapepa eHDPE akareruka uye anochinjika zvakanyanya: Mapepa eHDPE ane huremu hushoma pane hwemvura, zvichiita kuti zvive nyore kuisa nekutakura. Anogonawo kubatanidzwa zvakanaka kuburikidza nekubatanidza nekupisa kuti agadzire chimiro chakasimba uye chakabatana.
5. Yakasvibirira uye Yakachengeteka Kunharaunda, Inogona Kudzokororwa 100%:Zvinhu zveHDPEinogona kudzokororwa zvachose 100%, zvichiita kuti ive chinhu chakasvibirira uye chisina njodzi kune zvakatipoteredza.
6. Nguva Yekushanda Kwenguva Refu uye Mari Dzishoma Dzekugadzirisa: Mapepa eHDPE haadi kugadziriswa kwekudzivirira ngura kana kudzivirira zvipembenene muhupenyu hwavo hwese, zvichikonzera mari shoma yekuchengetedza.
Chiteshi chengarava chinoshandisa mafendi ehuni, mushure memakore akati wandei, chakatsemuka nekuda kwekuoma kwakawanda uye kunyura mumvura yegungwa kwenguva refu, zvichida kutsiviwa nguva nenguva. Mafendi eHDPE akabva ashandiswa panzvimbo pezvo. Kusimba kwawo kunobvumira kuti unyatsotora uye kuparadzira simba rekurovera kubva pachikepe, uye kuramba kwayo ngura uye kuramba kwayo UV kunoita kuti machira eHDPE arambe aine ruvara rwawo kwenguva yakareba, asingade kugadziriswa kwenguva refu uye kuderedza mari yekushandisa pachiteshi.
Mumapurazi esalmon ekuUK, hombePepa reHDPEMafuremu anoita kuti nzvimbo dzekurima dzive dzakavhurika uye mvura yakanaka. Mafuremu aya haaori, uye nzvimbo dzawo dzakatsetseka dzinobvisa kudiwa kwekuchenesa nzvimbo dzawo.
Kubva pazvidzitiro zvemadhoki kusvika kuzvivakwa zvekurimwa kwemvura mugungwa, zvinhu zveHDPE zvaratidza kushanda kwayo kwepamusoro sezvinhu zvakakwana kune nharaunda yakaoma yegungwa. Nekukura kuri kuita hupfumi hwegungwa, machira eHDPE, ane hunhu hwawo hwakachengeteka, hunogara kwenguva refu, hune hushamwari kune nharaunda, uye husina mari yakawanda, achaita basa guru mukukura kwehupfumi hwegungwa, kusanganisira mapuratifomu ezuva remangwana emagetsi ekunze uye madhoki ane hushamwari kune nharaunda.
